They've created the most fierce weapons and zords ever. Will Demonella be the first ever villain to defeat the rangers? Or can the rangers win another battle? Find out on Power Rangers Speed Chasers!
Orvon - Orvon can still give new powers and zords to the new team of rangers and still continues to mentor them throughout the battles to come.

Jaycee - Jaycee is Officer Johnson's niece. She is friends with Ella and Chloe and Dominic also has a crush on her.
Demonella - Demonella is the new villain in town. She is most likely the diva of space. She has known Orvon for years until she got turned to evil by another villain she had battled a long time ago.
Vikus - Vikus is the villain who always has a plan. It was he who turned Demonella into a villain because he thought she had potential to be one instead of being a good guy.
Makicarg - is Vikus's sidekick. Most of the time, he caters to his and Demonella's wishes. Makicarg is also the one who creates the monsters that the Power Rangers Must battle.
Olaf - Olaf is the "kid" of the group. Although he is a villain, he annoys the others due to his clumsy and childish ways.
